AZ23C36-7

Overview

The AZ23C36-7-F is a dual surface mount Zener diode manufactured by Diodes Incorporated, housed in an SOT-23 package. It features a common anode configuration with a maximum power dissipation of 300 mW. The nominal Zener voltage is 36 V, with a range of 34 V to 38 V at a test current of 5.0 mA. Maximum Zener impedance is 90 Ω at IZT = 5.0 mA and 250 Ω at IZK = 1.0 mA. The typical temperature coefficient is +0.090 %/°C. Operating and storage temperatures range from -65 °C to +150 °C.

Feature Summary

• Dual Zener diodes integrated in a single common anode configuration within a compact SOT-23 package.
• Qualified for high reliability applications meeting JEDEC standards and AEC-Q101 ESD ratings (HBM 8kV, MM 400V).
• Manufactured using lead-free, halogen-free, and antimony-free materials compliant with RoHS directives.

Applications

• Automotive electronic circuits requiring specific change control and high reliability.
• Voltage reference and regulation in surface mount assembly processes.
• Electrostatic discharge (ESD) protection interfaces.

Procurement Notes

Verify the complete part number includes the suffix '-7-F' for commercial grade availability in tape and reel packaging. Confirm that the application environment does not require the automotive Q-suffix variant if AEC-Q101 qualification is mandatory. Ensure design reviews account for the specified thermal resistance and derating curves provided in the official datasheet.

Selection Notes

Select this component when a dual common anode Zener array is required in an SOT-23 footprint. The 300 mW rating supports moderate current loads. Verify that the 36 V breakdown voltage aligns with circuit requirements and that the positive temperature coefficient (+0.090 %/°C) is acceptable for the operating temperature range.

Part Context

This device belongs to the AZ23C series, which covers Zener voltages from 2.7 V to 51 V. All variants share identical mechanical dimensions and pin configurations, differing only in electrical characteristics such as breakdown voltage and impedance. The series is designed for automated insertion and general-purpose voltage regulation tasks.

Replacement Considerations

Publicly confirmed substitutes include AZ23C36-7-F (Diodes Inc.), AZ23C36-G3-08 (Vishay), and AZ23C36-AU_R1_100A1 (Panjit). Cross-referencing exact impedance and leakage specifications is recommended before substitution.
